Earnings per Share¹ (EPS) for the second quarter of 2011 was $0.37, a 19.4% increase from the $0.31 reported in the second quarter of 2010. Excluding NBCUniversal transaction and related costs and a $137 million non-cash, non-recurring income tax charge resulting from a state tax law change, EPS increased 27.3% to $0.42 compared to $0.33 in the second quarter of 2010 (see Table 4).

Free Cash Flow (excluding any impact from the Economic Stimulus packages) increased 12.2% to $1.5 billion in the second quarter of 2011 compared to $1.4 billion in last year’s second quarter.

increases in the licensing of owned content from the cable production studio.
